Top Questions from Buyers
Q1: I need 2 tons per hour — should I get YGM75 or step up to YGM85?
For 2 t/h at 200 mesh on limestone, YGM75 (1-3 t/h, 18.5 kW) is a comfortable fit — it has been running at 2.8 t/h consistently in our case study. Step up to YGM85 (1.2-4 t/h, 22 kW) only if you expect to grow beyond 3 t/h within 2 years. The YGM75 has the lowest total cost per ton in its class: 18.5 kW for 1-3 t/h means approximately 6-18 kWh/t depending on fineness.
Q2: Do I need a separate crusher before feeding into the YGM75?
The YGM75 accepts feed up to ≤15 mm. If your raw material is already crushed to below 15 mm (from a jaw crusher or hammer mill), it can be fed directly via the bucket elevator. If your feedstock is larger, we recommend a small jaw crusher (e.g., PE-150×250, 5.5 kW) as pre-processing. We can include it in the complete line package — ask us for a turnkey quote with all auxiliary equipment.
Q3: The YGM75 floor space is only 4300×3500 mm — is there enough room for maintenance access?
The YGM75 is the most compact production-grade mill in the YGM series, ideal for sites with space. The machine footprint is 4.3×3.5 m, but for full maintenance access (roller/ring replacement clearance, classifier removal), you need a total area of approximately 50 m². Our customer’s complete line (crusher + elevator + mill + collector) fits within a 50 m² plant. We provide a detailed layout drawing with order confirmation.

Working Process of YGM Grinding Mill
1. Feeding:Raw mineral materials are evenly and continuously fed into the grinding chamber via the feeding device under stable feeding speed.
2. Grinding: Driven by the main motor, grinding rollers and grinding ring squeeze, impact and grind raw materials repeatedly into fine powder particles.
3. Classification: High-speed air flow cooperates with the built-in p owder classifier to screen and separate qualified fine particles from coarse ones precisely.
4. Collection: Qualified fine powder is transported by airflow into the dust collector and collected as finished mineral powder products.
5. Re-circulation: Oversized unqualified particles fall back to the grinding area automatically for secondary regrinding until reaching required fineness.

FAQ
1. What is the minimum plant space required for a YGM75 installation?
The YGM75 has a compact footprint of just 4300×3500×5100 mm. Including auxiliary equipment (feeder, collector, piping), a total floor area of approximately 50 m² is sufficient for a complete
2. Can the YGM75 be upgraded to increase capacity later?
While the YGM75 is optimized for 1-3 t/h, customers looking for future expansion often start with the YGM85 which shares the same 3-roller layout but offers 1.2-4 t/h capacity. We can help you choose the right model based on your 3-year growth plan.
3. How long does spare parts delivery take for the YGM75?
We maintain a comprehensive inventory of YGM75 wear parts (rollers, rings, classifier blades). Standard spare parts ship within 3-5 working days. For urgent requirements, we can arrange express air freight delivery to most countries within 7-10 days.
4. Is the YGM75 suitable for wet or sticky materials?
The standard YGM75 is designed for dry grinding with material moisture below 6%. For materials with higher moisture content, we recommend equipping the system with a hot air generator to pre-dry the material during the grinding process.
